Abstract
Recently, the plane jct impingemcnt system is widely used in the heat and mass transfcr industrial processes. It presents a compact efficient system that leads to decrease size of the machine used.
Experimental and numerical investigations are presented in the present thesis for the flow fields of different plane jet configurations. The experimental studies are for: the plane confined offset jet, the plane inclined offset jet, the plane ventilated offset jet and the plane confined offset jet with opposite wall. The studies aim to present the flow field characteristics and its controlling parameters for each plane jet configuration.
The flow field of the confined offset jet is divided into three region the recirculation region, the impingement region and the wall jet region. The experiments were for the impingement region and the wall jet region The effect of the offset ratio on the flow field parameters and the surface pressure distribution was investigated. The flow field parameters studied are: the attachment point, wall jet location, maximum velocity decay and the jet spreading.
The plane inclined offset jet flow field is divided into three flow field regions: the recirculation region, the impingement region and the wall jet region as these of the confined offset jet without inclination but with some changes. The effect of the jet inclination angle on the flow field parameters and the surface pressure distribution was investigated. The attaellillenl poinl, wall jet location, maximum velocity decay and Ihc jet spreading are studied for different jet inclination angles and compared to the values indicated for the jet without inclination
For the plane ventilated offset jet the experiments covered the attachment region and the wall jet region and part of the free jet region. The effect of the ventilation distance on the flow field was studied. Also, the effect of the offset ratio on the attachment point, wall jet location, maximum velocity decay, the jet spreading and the surface pressure distribution was investigated
The flow field of the plane confined offset jet with opposite wall consists of a developing region through which the jet attaches the near surface then attaches the far surface then the jet is developed to form the apparent flow in closed conduit region. The experiments covered the entire flow regions and the surface pressure distribution on the lower surface was measured. The effect of the opposite wall offset ratio on the flow field and the surface pressure distribution on the lower surface was investigated for constant lower surface offset ratio.
Finally, a numerical study for the confined offset jet and the ventilated offset jet was performed. The pressure correction algorithm was used in the study using FLUENT 4.]] code. The study presented the flow field regions that was not covered in the experimental study and more details about the flow field regions that were studied experimentally
